-6x + 9y = 21 . . . (1)
10x - 3y = -23 . . . (2)
(2) x 3 => 30x - 9y = -69 . . . (3)
(1) + (3) => 24x = -48 => x = -48/24 = -2
From (1), -6(-2) + 9y = 21 => 9y = 21 - 12 = 9 => y = 9/9 = 1
Threfoe, x = -2 and y = 1
Answer: 33/5 x 4/21 = 44/35
Answer: The answer is C.
Step-by-step explanation:
Because in the theory of the outcome is a 50/50 chance landing heads or tails. So, the theorectical probability is 1/2. Now the experimental must be 11/20.
Anwser - c 0.70 I pretty sure
